Femtosecond laser has been approved by the Chinese Food and Drug Administration for corneal surgery since 2006, with its ultra-short pulses, ultra-powerful instantaneous power and highly accurate targeting. The computer-controlled femtosecond laser can create a very precise corneal flap, and excimer laser myopia correction perfect combination to achieve the field of myopia correction “all-laser” concept, making the surgery safer. Some patients are unable to undergo traditional surgery because their myopia is too deep and their corneas are too thin. Because the femtosecond laser technology can create thinner flaps, it can increase the range of surgical treatment for myopic patients with thin corneas, making it possible to undergo excimer laser surgery that was previously unacceptable.
